Characterization of a thermal interface material for burn-in application

Abstract

A series of tests to characterize the suitability of a material as a thermal interface for burn-in applications were generated. These tests include thermal resistance at elevated temperature, thermal resistance as a function of cycle number, mechanical cycling with and without shear, extended high temperature exposure, residue measurements, mechanical compliance measurements, and tensile and shear strength measurements. Results from testing were used to optimize an in house thermal interface material to withstand repetitive burn-in cycles without requiring replacement.
